In one aspect, an implantable shunt system 100 is disclosed that, in one example implementation, includes a resilient member 108 and a connected fluid regulating device 116. The fluid regulating device selectively permits fluid flow through an opening valve 105 of an implantable shunt according to an adjustable opening pressure. The opening pressure is proportional to an amount of tension on the resilient member. One or more tension sensors 110a, 110b that are connected to the resilient member measure an amount of tension on the resilient member. The tension sensors generate tension data that corresponds to the measured amount of tension. The system further includes a communication unit 132 with a transmitting unit that transmits the measured data over a communication link 133.
